Dhirubhai Ambani International School
Full-continuum school in BKC offering ICSE, IGCSE, and IB Diploma from LKG to Grade 12, founded in 2003 by Reliance Foundation. Ranked 9th globally for IB DP results in 2025 - the only Indian school in the world top 10.
In brief
DAIS is the school built by Reliance Industries and opened in 2003, with Nita Ambani as chairperson. Around 2,800 students on a BKC campus in Bandra East, running ICSE, IGCSE and the IB Diploma, and ranked the top international school in India by EducationWorld for more than a decade.
The campus sits on Trident Road in BKC, with a 6:1 student to teacher ratio and accreditations from CIS and NEASC. ICSE is being phased out, with the last cohort sitting boards in March 2026. Fees range from around INR 1.7 lakh in the early years to nearly INR 10 lakh in the Diploma. IB Diploma results sit consistently among the highest in India.
Families talk about academic rigour, world-class facilities, and routes into elite global universities. The recurring caveats are a wealth profile among the most concentrated of any Mumbai school, the social pressure that comes with it, and admission that is genuinely hard outside Reliance circles. Best fit for academically able children whose families can carry the fees and want the strongest Diploma launchpad in India.

Reviews
- DAIS is the most-discussed school in this batch. Public signal sits, Quora and Justdial, with consistent themes across them.
- Academic intensity and outcomes are the headline strength. Parents and students cite IB Diploma scores and university destinations including the Ivy League; one Reddit comment said "DAIS, oberoi, ABWA etc like those have most ivy league selections in India".
- Academic pressure is the headline weakness. Quora respondents call it "unreal" and "not conducive", with limited room to explore personal interests, alongside r/JEE comments contrasting Malabar Hills students with Dharavi peers.
- Fee discussion is unusually concrete. Public posts cite published annual fees of around 9 to 15 lakh, with one r/Frugal_Ind comment alleging that admissions outside the public process require donations of more than 50 lakh and connections.
- Wealth and social-fit themes recur. Parents and observers describe a tight elite circle, with status display flagged as a daily-life feature.
